To all whom it on y concern:

Be it known flat I, ALBERT B. HERRICK, a citizen of the United States, and a resident of Cleveland, county of Cwyahoga, and State of @hio, have inventor-g. a new and useful Improvement in Generating Mechanism, of which the following is a specification, the principle of the invention being" herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is mechanism for generating an electro-mot ve force, such mechanism being adapted particularly for use in an igniter which will be attached to an engine cylinder in the position usually taken by the spark plug, the compression of the engine being used to furnish the power necessary to perform the movements required in the generating mechanism; in other words, the generating mechanism is a self contained magneto adapted to be automatically operated by the compression of the gases in the cylinder of an internal combustion engine, although it will be understood that other uses for'the mechanism will readily suggest themselves.

The present application relates to the induction mechanism described in my co pending application, Serial No. 733,976, filed November 29, 1912, now issued into United States Patent No. 1,174,145, dated March 7, 1916, from which the present application is divided.

In said annexed drawing Figure 1 is a central vertical section. through one form of my invention; Fig. 2 is a section on the line 22, in Fig. 1; Fig. 3 is a view in perspective of the armature and the contact members attached to the ends of the magnet Figs. 4 and 5 are end elevations of the mechrnism showing the armature in its upper and lower position; Fig. 6 is a diagram showing the method of wiring the device; F; 2. 7 is a side elevation oi".a modified form 0i my invention; Fig. 8 is a view similar to Fig. 7, but showing the armature in its raised position; Figs. 9 and 10 are views corresponding to Figs. 7 and 8, showing a third form of the invention, and Fig. 11 is a section on the line 1111, in Fig. 1.

In the construction shown in Fig. 1, I at tach to a hollow spark plug 1 a brass plate or base member 2 upon which will be mounted the contacts 3 and 1 attached to the ends of a magnet 5. T he'magnet is preferably laminated. or sectional, as shown in Figs. 1 and 2. Upon the top of themembers 3 and 4, I attach a second brass plate 6 upon which there is mounted a lubricating cup 7, the construction of which need not be explained in detail.

The magnets 5 are preferably of U-shape and extend horizontally around an armature 8, consisting preferably of a primary coil 9 only, and a soft iron core 10. The armature is provided at its top and bottom with plates 11 and 12 attached to th core. To the bottom platelQ is attached a piston member 13 slidably mounted in the hollow chamber formed in the spark plug and iii) adapted to be operated by the compression in the engine cylinder. The piston will be lubricated from the il cup by suitable mechanism. Attached to the piston 13 are a spring arm 14: terminating in a contact 15 and a rod 16 terminating in a contact 17, adapted t normally engage the contact'15, thus forming a closed circuit, as both contact members are suitably connected to the armature, the connection being illustrated in Fig. 6. The spring arm it extends around the contact 15 and engages a collar 18 slidably mounted upon a rod 19 extending clownwardly from the end of the spark plug. The end of the rod 19 is threaded and is engaged by a stop in the form of a nut 20.

'eXtends vertically between the same inclosing a rod 23 provided with a handle :24 and attached at its lower end by means of a pin 25 to a lever 26 which is pivoted intermediate its ends about a pin 27 mounted in an extension of the bottom member 2. The lever 26 terminates in a yoke 45, each arm of the yoke engaging a pin 28 which is slidably mounted at the bottom of the armapurpose may be similar to that described in my co-pending application, Serial No. 700,594, filed May 31, 1912, now issued into United States Patent No. 1,177,701, dated April 4, 1916, or may be of the construction shown in Figs. 1 and 2. I

In Figs. 9 and 10, I show a third form of the invention in which the'arrangement of the teeth on the core and the polar faces on the magnet differ from that shown in the two previous forms. In this form I also show my preferred form of piston member and hollow chamber in the spark plug. The

form of the polar faces and the teeth is sub stantially like that shown in Figs. 7 and 8, except that the magnet is cut away to form the polar faces 90, 91, 92 and 93, which are adapted to be engage-,(Lby the projecting teeth 94, 95, 96 and 97 on the core. The direction of the magnetic flux will be reversed by the operation of the armature, the direction of the flux being shown by the arrows in Figs. 9 and 10. The spark plug is hollowed out to form an enlarged chamber 100 which is provided with a beveled shoulder 101 at its upper end and an oppositely beveled shoulder 102 at its lower end. The piston is provided with a complementary beveled portion 103 adapted, when the piston is raised, to contact the shoulder 101, thus providing a secure closure of the aperture in the spark plug and preventing the entrance of any of the hot burning gases into the space surrounding the armature and the magnets. In this way the life of the magnets and the armature is increased, as the action of the hot gases upon the same tends to'break down the insulation and to de-magnetize the magnets.

The present invention provides an automatically operated generating mechanism in which the coil is reciprocated to cause the establishment of a current therein, which is secured by the arrangement of the magnet and the contacts on the magnet and core, the arrangement being such as to cause a reversal of the magnetic flux through the coil.

The travel of the coil is slight and the improved type of piston and chamber prevent the escape of any gas from the engine cylinder.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as lowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a generator, the combination-of a permanent field magnet having spaced contacts thereon, a reciprocably mounted armature having complementary spaced contacts, and means for reciprocating said armature to change the engagement of said contacts and revlerse the direction of flux through said 001 2. In a generator, the combination of a permanent fieldmagnet having spaced contacts thereon, a reciprocably mounted armature having complementary spaced contacts, adapted to engage with saidcontacts on said magnets, reciprocation of said armature being adapted to change the contacts in. en-

gagement to reverse the direction of flux through said armature, and means for reclprocating said armature.

3. In a generator, the combination of a.

permanent field magnet having its poles ad- ]acent -one another, two spaced contacts formed on each such pole of said magnet, an armature reciprocably mounted between such poles, complementary spaced contacts mounted on said armature, reciprocation of said armature being adapted to change the contacts in engagement to'reverse the direction of flux through said armature, and

' means for reciprocating said armature.

- 4. In a generator, the combination of a permanent field magnethaving its poles adacent one another, two spaced contacts formed on each such pole of said magnet, an,

armature reciprocably mounted between such poles, complementary spaced contacts mounted on said armature, said armature having a winding, reciprocation of said magnet being adapted to change the contacts in engagement to reverse the direction of flux through said armature, and means for reciprocating said armature.

l9Signed byme this 23 day of November,

ALBERT B. HERRICK.
